Despite the excitements over virtual reality (VR) and the availability of dozens of high resolutions 360° VR video cameras, consumer adoption of VR video has been very slow. One of the major obstacles is the distribution of VR content which requires much higher network bandwidth than that commercially available. In this project, novel algorithms and processing architecture will be developed to optimize VR video streams for efficient live streaming of VR video. In additional, machine learning will be applied to identify Region-of-Interest (ROI) to realize intelligent video streaming. The proposed algorithms will be implemented on FPGA platform, providing a hardware-accelerated solution for real-time optimization of VR video streams.
This project aims to produce a real-time solution for optimization of 360° VR video for efficient streaming. It would facilitate the wide scale adoption of VR video, providing new growth opportunities for Hong Kong digital marketing and media production industry. Augmented with the automatic detection of ROI, it would provide an effective solution for utilizing 360° VR video in live monitoring of public spaces and critical infrastructure, enabling various smart city applications to secure and manage our city. In the longer term, it could enable immersive communication, allowing stronger connections between people at remote locations.
